Introduction to Global Oceanography and Marine Ecosystems

The global ocean covers over seventy percent of our planet, regulating our climate and supporting a vast diversity of life. Understanding the ocean's fundamental systems is essential for anyone interested in marine biology, environmental science, or global conservation. Through this text-only course, you will build a solid foundation in oceanography, exploring how physical, chemical, and biological processes shape marine environments. You will transition from having a basic curiosity about the sea to understanding the complex systems that sustain global life. What you'll learn: - Learn the foundational principles of chemical and physical oceanography, including currents and tides - Explore the diverse zones of marine life, from coastal estuaries to the deep ocean floor - Understand the critical role of oceans in global climate regulation and carbon cycling - Examine modern environmental challenges, including ocean acidification and plastic pollution - Discover sustainable ocean management practices and the concept of the blue economy The course begins with essential terminology and the physical properties of seawater before moving into marine ecosystems, food webs, and human interactions with the marine environment. This course is designed for complete beginners, students, and environmental enthusiasts who want to explore marine science without any prior scientific background.
